FEED- INDICATOR FOR LUBRICATORS.

y SPECIFICATION forming part Of Letters Patent No. 601,204, dated March22, 1898.

' 'Application filed May 22, 1897. Serial No. 637,786. (No model.)

To @ZZ whomv t may concern:

Be itknown that I, DANIEL L.- BEACH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented' cer-tain new and useful Improvements inl Feed-Indicators forLubricators; andl do hereby declare the following to be a full, clear,and exact description of the lsame, reference being had to theaccompanying drawings, forming a part of this specification.

The present invention relates to mechanical means for affording avisible indication of the amount of oil that is fed from a lubricatorduring use, the object of the present improvement being to provide asimple and efficient attachment for lubricators, either sight-feed orotherwise, whereby the position of theoilregulating valve is indicatedupon a dial, and thus afford a guide for the operator in a subsequentsetting of the valve to attain a like feed or one approximately fasteror slower. I attain such object bythe construction and arrangement ofparts illustrated in the ac'- companying drawings,l in which- Figure 1is an elevation of a portion of a sight-feed lubricator to which thepresentin- Vention is applied; Fig. 2, a sectional elevation at lineFig.v 3, of the same; Fig. 3, a horizontal sectional elevation at lineoc' Fig. 2.

Similar numerals of reference indicate like parts in the differentviews.

Referring to the drawings, 1 is the body of a sight-feed lubricator, 2,the Ysight-feed tube; 3, the feed-tube base, and 4 thestem of theregulating-valve by which the iiow of oil is controlled.

5 is a dial-plate secured to the base 3 in a detachable manner by meansof side extensions 6 and end plate 7, which is secured to the extension6 by screws, as shown.

8 are lugs on the extensions 6, that are adapted to engage against theforward face of the base 3, and said lugsv are positioned,'as shown, soas to support the dial-plate 5 out of contact with said base.

. 9 is a hand or pointer of the dial-plate, pivoted at the lower end ofthe same and which has its movement limited by stop-pins 10 onsaiddial-plate, as shown. l

' 11 is aspring secured to the dial-plate and to the hand or pointer,the tendency of which is to move said hand to the zero-mark of theindex-plate.

12is the tail extension of the hand or pointer, having a thin flexibleformation and an inturned or bent extremity 13, as shown.

14 is a collar removably secured to the stem 4 of the regulating-valveby screws or other likemeans,

1 5 is a vertical member, preferably of the triangular formation shown,that is secured to the collar 14 of the regulating-valve and adapted toengage the tail extension 12 of the pointer 9, so as to move saidpointer across the dial as the stem of the regulating-valve is turned toadj ust the iiow of oil.

The present improvement`is intended to operate with a fractionalrotation of the regulating valve-stem, and thus afford a very sensitiveindication of the same, and accordingly itis intended that the saidregulatingvalve be adjusted approximately to the required opening beforethe present device is set to indicate in a sensitive manner the furtheradjustment of the Valve; yand to this end a material feature of thepresent invention consists in the heretofore-described flexibleformation of the tail extension 12 of the hand or pointer 9, combinedwith the vertical member 15 on the collar that is secured to the stemofthe regulating-valve, and which member is preferably of the triangularform shown in that such construction admits of the ready 'passage of onepart past the other in the preliminary rotation of the valve-stem ineither direction to attain the desired flow or feed of the lubricantfrom the lubricator.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination with a lubricator, and its regulating-valve of amember 15, secured to the stem of the valve, a stationary indexplate,and a pointer pivoted on said indexplate and having a tail or extension12, adapted to be operated by the member 15, substantially as set forth.

2. The combination with a lubricator, and its regulating-valve, of amember 15 removably secured to the stem of said valve by a collar 14, astationary index-plate, and a pointer pivoted on said index-plate, andhav- IOO infr :L tail or extension 12 :ida` ted to be o er- D 7 p :Ltedby the member 15, 'substantially :Ls set forth.

3. The combination with :L lubrioator, :Lnd its regulating-valve, of :Lmember 15, seeured to the stem of the valve, :L stationary indexplate,:Lnd :L pointer pivoted on said indexplute :Lnd provided with :L t:Lilor extension 12, the extremity 13 of which is inturned, said tail 13being :LdLLpted to be opera-ted by the member 15, substantially :Ls setforth.

l.

5. The Combination with :L lubrioator, :Lnd its regulating-valve, of :Lmember 15, secured to the stem of said valve, :L stationary indexpl:Ltesecured to the feed-base 3, of the lubrie:Ltor, by extensions 6, :Lndend plate 7, :Lnd :L pointer pivoted on said index-plate :Lnd providedwith :L tzLil or extension 12, adapted to be operated by the member 15,substantially :Ls set forth.
